Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600852, here are decompositions:

29 + 31600823 = 31600852
53 + 31600799 = 31600852
131 + 31600721 = 31600852
149 + 31600703 = 31600852
233 + 31600619 = 31600852
359 + 31600493 = 31600852
401 + 31600451 = 31600852
431 + 31600421 = 31600852

Showing the first eight; more decompositions exist.
